“one of Florida´s newest state parks”

Located in one of Florida´s newest state parks, this crystal clear, first magnitude spring is a popular spot for swimming. About 82 feet wide and 25 feet deep, the spring bubbles up into a limestone basin along the west bank of the Withlacoochee River. Scenic woodlands of mixed hardwoods and pines create a picturesque setting for picnicking, paddling, and wildlife viewing. Madison Blue Spring is approximately ten (10) miles east of Madison on the west bank of the Withlacoochee River. From Madison, drive east on State Road 6 to the Withlacoochee River. Turn south on the west side of the bridge at the park sign. The entrance to the spring is 525 feet south of the highway.
If you're looking to get away from the crowded beaches in Florida, the hidden swimming hole at Madison Blue Springs State Park is the spot for you! It's tucked away in a shady forest, along the banks of the Withlacoochee River, making it the perfect place to cool off on a steamy Florida afternoon. It's one of the states' newest state parks, having been established in 2000. The park itself has picnic tables, bathrooms and even a shower that swimmers can use to hose off after a nice dip in the spring. They've even got a dock that you can jump off of-- cannonball! It also makes for amazing scuba diving-- you can.
The limestone basin is 82 feet long, 25 feet deep, and totally filled with refreshing, crystal clear spring water. In fact, it's bottled-water-level refreshing; Nestle uses water from nearby springs on adjoining land for its bottled water brands. The water comes from a first-magnitude spring, which means it discharges at least 2800 liters of fresh H2O every second-- and it always stays around 72 degrees all year round!

Perfect way to spend an afternoon! They've got picnic tables, restrooms and showers so you really can make a day of it. Plus, check out that water! It's literally bottled-water fresh-- Nestle uses it for some of their bottled water brands :)

Definitely visit here if you live nearby. The water is so clear that you can see the small fish swimming 25 feet down. There is also a snack cart in the park that sells shaved ice, boiled peanuts and other tasty treats. Definitely worth the 5 dollar (2.50 for military) entrance fee!!
